The programming language used is Java and the question 4 related to the question 5 is also attached for reference. Write a java class called House with the following two private attributes, and threemethods:Attributes:1) type (String)2) height (int)The valid values of attribute "type" are: "Cabin", "Bungalow", and "High Rise".A house can be upgraded to the next type. For example, a house of type "Cabin" canbe upgraded to "Bungalow" which can be later upgraded to "High Rise". A house isnever downgraded.Methods:1) constructor that takes accepts two input parameters to initialize the attributes ifinput parameters are valid. The constructor should "ThrowIllegalArgumentException" with a reasonable message (Invalid House type or Invalidheight) if input parameter for house type is invalid or input parameter for height isless than or equal to 0. The constructor should include try/catch blocks and thecatch block should print the exception message and terminate program with"System.exit(1);".2) upgrade method that takes no input parameters. It doubles the height of a houseof type Cabin or Bungalow, then revises the value of type to next value (i.e., Cabin toBungalow, Bungalow to High Rise, and High Rise remains the same).For example, upgrade() method will update a house of type "Cabin" with height200 to next type "Bungalow" with height value of 400.For example, upgrade() method will update a house of type "Bungalow" withheight 400 to next type "High Rise" with height value of 800.If the type of house is "High Rise", the upgrade() method should throw anIllegalArgumentException with message "High Rise house cannot be upgraded".The upgrade() method should include try/catch blocks, and the catch block shouldprint the message and allow the program to continue executing.3) toString method which returns a string with first character of type and height.e.g., tostring() should return a "C200" if the house is of "Cabin" with height 200.tostring() should return a "B500" if the house is of "Bungalow" with height 500.tostring() should return a "H1000" if the house is of "High Rise" with height1000. Map ClassCreate a class called Map that uses the class House which was developed inquestion 4.The Map class should include the following two private attributes:1) private static House []] houses; // (as 2D array of houses of size MxN.Example: 8x7 array would be declared as House [8][7].3x4 array would be declared as House[3][4], etc.2) private static final String FILE_NAME = "house.txt";Write the following methods. You must determine if they should be private/publicand static/non-static:1) loadHouses() method that takes no input. This method should initialize the housesattribute by putting the house data into the attribute. The data should be loadedfrom the text file which is given in the FILE_NAME attribute. The data format in thehouse.txt is described as follows:house.txt file contents are as follows data lines:Cabin:5, Cabin:1, Bungalow:9, High Rise:11Cabin:2, Cabin:4, Bungalow:8, Bungalow:10High Rise:13, Cabin:3, Bungalow:6, Bungalow:7High Rise:15, High Rise:14, High Rise:12, High Rise:16After calling loadHouses(), the houses are loaded in the 2D array, such thatSystem.out.println(Arrays.deepToString(houses));should print the following:[[C5, С1, В9, Н11]), [C2, С4, В8, В10], [Н13, СЗ, В6, B7]), [Н15, Н14, Н12, Н16]]2) A method upgradeHouses that takes two integers (first being row, and secondbeing column) of houses. The entire row and column should be upgraded (each houseby only once).Example:Before calling upgradeHouses method ifSystem.out.println(Arrays.deepToString(houses));prints the following:[[C5, С1, В9, Н11]), [C2, С4, В8, В10], [Н13, СЗ, В6, B7]), [Н15, Н14, Н12, Н16]]after calling upgradeHouses(1,2) method, theSystem.out.printIn(Arrays.deepToString(houses));Should print the following:[[C5, C1, H18, H11], [B4, B8, H16, H20], [H13, C3, H12, B7], [H15, H14, H12, H16]]3) A main method with the following statements:• all Map.loadHouses() method.• print the houses array with:System.out.println(Arrays.deepToString(houses);• call upgradeHouses(1, 2);• print the houses array with:System.out.println(Arrays.deepToString(houses));

Question

The programming language used is Java and the question 4 related to the question 5 is also attached for reference. Write a java class called House with the following two private attributes, and threemethods:Attributes:1) type (String)2) height (int)The valid values of attribute &#34;type&#34; are: &#34;Cabin&#34;, &#34;Bungalow&#34;, and &#34;High Rise&#34;.A house can be upgraded to the next type. For example, a house of type &#34;Cabin&#34; canbe upgraded to &#34;Bungalow&#34; which can be later upgraded to &#34;High Rise&#34;. A house isnever downgraded.Methods:1) constructor that takes accepts two input parameters to initialize the attributes ifinput parameters are valid. The constructor should &#34;ThrowIllegalArgumentException&#34; with a reasonable message (Invalid House type or Invalidheight) if input parameter for house type is invalid or input parameter for height isless than or equal to 0. The constructor should include try/catch blocks and thecatch block should print the exception message and terminate program with&#34;System.exit(1);&#34;.2) upgrade method that takes no input parameters.
